Cannot Activate License via Project Manager

When I get to the "Activate a license" screen in the Project Manager, the radio button for email/password is greyed out. I only have the option to use a downloaded license. This has been going on for the past few days, and I'm still having the issue after downloading 4.2.1650.0.

I understand that I can download my licenses via the website, but what I'm looking to do is download the Community Edition, which as I also understand, can only be requested via the Project Manager after logging into my account.

I'm running as admin, turned off my firewall and AV and still no go.

Thanks,
Ed

Eh - nevermind - posted too soon. Apparently, it WAS my firewall. Still strange tho, in that I don't seem to have any firewall entries specifically blocking the Project Manager at the application level, have all outbound connections as allowed by default, and was never prompted to open ports - but oh well I guess.
